Well, if I am not wrong, JSF components are platform-independent... If Oracle's library does not depend on proprietry stuff, then it will be possible to add those componentsto WSAD JSF Platform... It's better to have a look at the site that you got those Oracle's JSF components library and find some documents about them...

Yes Masoud you can use Oracle ADF Faces components with another IDE, I'm working now with this controls and the Oracle's Blaf framework is not too bad but, they are too heavy and there aren't wysiwyg even in JDeveloper 10G (remember ADF Faces is an early access). I think the WSAD 5.2 JSF are much better.
